So my rear tire wasnt mounted right, and i wrecked my xj 650

So i leave the shop last night, new tire on the back, i bought the tire at a swap meet, and had a shop put it on. So i come out of this corner and i just completely lose control of the rear end of the bike because its wobbling violently from side to side and it finally just throws me off the bike slides fifty feet, and then i slide probably thirty feet.
But i cant really figure out what happened, because the tire is still on the bike, but where the lip of the tire is supposed to be tucked inside the lip on the wheel, it looks like the lip of the tire is sitting right on top of the lip of the wheel, but its like that the whole way around on each side, it looks like thats almost how its supposed to be.
So now something up front is bent up pretty bad, when the handlebars are straight, and the triple trees are straight the front wheel is pointing way to the right, and the left highway bar mounts totally broke off, and the handlebars are probably bent, it was dark, i couldnt tell hardly anything last night.

So my question would be...Do you guys think i bent my forks? or just knocked the wheel sideways on the forks?
Also do you think the tire is on right? i havent rode it since then, but i can see the tire is still holding air

any help at all would be greatly appreciated, i have been reading this forum for a few months, but finally joined today

 

Sorry to hear about all that, good to hear youre not in the hospital.
The downside is they installed a tire that you brought in to them.
Is it possible the tire seller "greased up" the tire to make it look pretty?
(with tire shine, tranny fluid, ETC)
Tell us the 4 digit date code- - - like 3402- - would be 2002

The front fork pinch bolts (6 of them) need to be loosened, the tire straightened, and re-pinch. Then you can start to figure out if they are bent. Get a really big guy to bend your bars back.(for now).

And Welcome to the site !!

 

Alright cool cool, thats good to know. Im not sure about the numbers i am at work now, and then im riding to lake of the ozark bikefest on my dads 82 virago Thats really good to know about the pinch bolts, i will try that as soon as i get back from the rally. I really hope the forks arent bent, ill have to get it to the shop i normally go to and have them take a look at it. By the way dude im sortof in love with your xj, i abosolutely love the big fairing and the trunks! i would love to do that to my bike!

 

sneeky where you located? someone on here may be able to help with the work instead of a shop and save you some $$$.

 

Were you going too fast for having a new tire installed? New tires contain a mold release compound that can't be removed except by riding and wearing the tire in a little. Basically, the same twists and turns you can do with your older tires can become very dangerous with a new tire within the first 100 miles or so.

 

If the tyre wasn't mounted right it would have been obvious as soon as you left the shop

How long from leaving the shop to before you tossed it away?

 

Ditto on what B-D-M said; new tires need to be "scrubbed" in by being very cautious the first hundred or so. Some riders actually sand the tread with sandpaper to speed the process; I plead guilty to wiping the tread with acetone to try to remove the outer layer of release agent. (It seemed to help) The same problem can arise from applying tire shine or AmorAll; if you're going to use the products, be meticulous about ensuring it only goes on the sidewalls, and NOT the tread.
If you can, snap some pix of the area in question and post them.

 

bum deal sneaky, but glad to hear your ok, new tires suck for the first hundred km's or so!! I almost put mine down after the last change too but I was lucky!! I've never changed a bike tire but I did car tires in a shop when I was younger I doubt it's that different and it's kind of hard to screw up and not know right away because the problem almost always shows up in the balance.

Re: So my rear tire wasnt mounted right, and i wrecked my xj

Any chance the rear tire could have been the wrong diameter for the wheel? It sounds more like the rear tire bead left the wheel than a slide due to mold release.

If the tire exited the wheel then that would certainly explain the squirrely performance. Even if the tire did not come off the bead he still indicates that the tire doesn't look like it might be mounted with the bead properly seated in the wheel.

 

Re: So my rear tire wasnt mounted right, and i wrecked my xj

I'm fairly certain the bead would not have seated and the tire would never have taken on pressure if it wasn't the right size.

Now, if the OP was claiming the wheel itself wasn't properly secured and caused the tire to come loose and wobble, I could almost see where he was coming from. In the mean time, I think he simply lost it coming out of a corner too fast.

 

Good points but he mentions that the bead looks like it is riding clear at the top of the ";ip" on the wheel. I guess the real question is whether the tire is still inflated or not.

Well, is there still air in the tire or is it flat.

BYW another good way to get rid of the mold release on a new tire is to run the tire for a few miles on gravel. In these days of budget cuts you should just about be able to pick any section of interstate to find enough gravel to scrub in a tire.

 

Re: So my rear tire wasnt mounted right, and i wrecked my xj

Can you post some pictures of this?

 

well that all helps very very much, i didnt know about the new tire thing and its probably a safe bet to say thats what happened, i wasnt taking the corner any faster than i regularly would, but it wasnt a slight curve either, i bet you guys are right.

About the tire, it still holds air, and when i rode it from the back of the tow truck to my buddies driveway it seems fine, i went up there yesterday and checked it out, and it is still very firm holding air, its just so so strange how the bead is like on top of/ overlayering the lip on the wheel, next time i am up there i will snap some photos and show you guys, its probably on right, it just looks really funny

Thanks so much guys! Your info has really helped!

 

Re: So my rear tire wasnt mounted right, and i wrecked my xj

Sounds like the tire didn’t get seated properly, if the bead line isn’t all the way out your outside diameter would be ok BUT the cross-section diameter would be out of round, probably causing a wobble when cornering.

Take several pictures around the bead showing the bead line, then take them to the shop that did the work, I bet they’ll say OOPPSS.

Re: So my rear tire wasnt mounted right, and i wrecked my xj

It would cause a wobble while it was going in a straight line and be apparent from the moment you started moving

 

Re: So my rear tire wasnt mounted right, and i wrecked my xj

HHhMMm
When I did it to myself it was more of a squirm (thinking to self "I don't like this new tire") in a straight line till I leaned over for a turn??

Maybe I didn't do as bad a job as the original posters shop?

Re: So my rear tire wasnt mounted right, and i wrecked my xj

Some tires have a lip that raises over the edge of the wheel that looks a bit like the bead. I just mounted one last week that looks like that.

 

some tires have a bead lock type system, the ones i just took off my police bike did.

 

Wow severely bummed for ya dude. Glad u are ok tho. Gives ponderance to doing purchases and installs rather than an all in one at a shop. Guess REALLY important to be sure size is correct and installation is as well. thanks for the heads up on the "coating"cause i goot do a rear wheel replacement and this is one trick pony that will be CAREFUL now. Does the ACETONE remove the coating effectively enuff without causin rubber damage?

 

Do not put anything on your tires. Just ride the bike and be careful for the first 100 miles or so. The mold release is not a coating that can be wiped off.
